# Mirage Avatar X API

> 数字人 X 说话头像视频，由你的音频和图像、视频或素材数字人参考驱动

根据 `audio_url`（3 到 180 秒）生成口型同步的头像视频。视觉内容来自 `video_reference_url`、`image_reference_url` 或素材 `avatar`；两者同时提供时，视频参考优先于图像。`avatar` 选项仅提供视觉内容，不提供音频。参考 URL 必须可通过 HTTPS 公开获取。

- Model id: `mirage-api/avatar-x/reference-to-video`
- Made by: Mirage
- Category: Lipsync & Avatars
- Output: video
- Price per second of your input audio: $0.30 / second of input audio (cheapest run $0.30 (300 API credits))
- Run: `POST https://api.doitong.com/v1/run/mirage-api/avatar-x/reference-to-video`
- Quote: `POST https://api.doitong.com/v1/quote/mirage-api/avatar-x/reference-to-video`
- Docs page: https://doitong.com/zh/developers/models/mirage-api/avatar-x/reference-to-video

## Pricing

Price: **$0.30 / second of input audio**. Price per second of your input audio: the input files are measured before the run (length, resolution, frame rate). The quote measures the same files and is exactly what the run charges.

The full example input below costs $3.00 = 3000 API credits (10 s input audio × $0.30).

Prices are the upstream price in USD, paid from the API balance in API credits (1000 API credits = 1 USD). `POST https://api.doitong.com/v1/quote/mirage-api/avatar-x/reference-to-video` with the same JSON body returns the exact price for that input; the quote is exactly what a run charges. Invalid input is never charged and failed or canceled requests are refunded automatically.

## Input parameters

Send either the canonical name or the native field name (not both). Canonical names are the same across models.

| Parameter | Canonical name | Type | Required | Default | Allowed values / range | Description |
|---|---|---|---|---|---|---|
| `audio_url` | `audio` | string (audio URL) | yes |  |  | 驱动生成视频的音频公共 HTTPS 地址，无需授权标头或 Cookie 即可访问。支持的音频格式包括 FLAC、Opus 或 Vorbis、AAC 或 ALAC、PCM WAV 或 AIFF，以及 MP3。文件必须包含单个单声道或立体声流，时长为 3–180 秒，大小不超过 64 MiB，采样率为 8–48 kHz。 |
| `video_reference_url` |  | string \| null | no |  |  | 参考视频 HTTPS URL，必须可公开访问且无需授权标头或 Cookie；文件必须包含恰好一个视频流，并至少包含一个适合作为参考的 1 秒片段；音频将被忽略。支持的文件组合为：.mp4、.mov 或 .m4v 搭配 H.264、H.265/HEVC 或 ProRes，或 .webm 搭配 VP8 或 VP9；时长必须为 1 到 120 秒，大小不得超过 1 GiB，显示宽高比必须与 9:16 或 16:9 之一相差不超过 5%。如果同时提供 image_reference_url，则优先使用视频。 |
| `avatar` |  | enum (string) \| null | no |  | `None`, `Ayesha`, `Ayesha (16:9)`, `Farhan`, `Farhan (16:9)`, `Giulia`, `Giulia (16:9)`, `Jasmine`, `Jasmine (16:9)`, `Luke`, `Luke (16:9)`, `Maya`, `Maya (16:9)`, `Michael`, `Michael (16:9)`, `Neha`, `Neha (16:9)`, `Tariq`, `Tariq (16:9)`, `Valerie`, `Valerie (16:9)` | 仅在未提供图像或视频参考时使用的素材视觉选择；None 和默认值都会保持未设置。该视觉不会提供音频，音频始终来自 audio_url。要选择视觉，请在 [avatar catalog](https://captions.ai/help/docs/api/actor-catalog) 中预览选项，并复制准确的 Avatar 值。 |
| `image_reference_url` |  | string \| null | no |  |  | 参考图像 HTTPS URL，必须可公开访问且无需 Cookie 或授权标头；提供 video_reference_url 后将忽略此 URL。接受单张 .jpg、.jpeg、.png 或 .webp 格式的静态图像，大小限制为 25 MiB、25 百万像素。较短边至少为 512 px，任一边不得超过 8192 px；宽高比必须与 9:16 或 16:9 相差不超过 5%。 |

File parameters (`audio`) take a public `https://` URL, a `data:` URI up to 10 MB, or the `file_url` of an upload from `POST /files`.

## Example input

Required parameters only:

```json
{
  "audio": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
}
```

A fuller example:

```json
{
  "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
}
```

## Run it

Set `DOITONG_API_KEY` to a key from https://doitong.com/developers/dashboard#keys. `?wait=20` returns the finished request in the same call when it is ready within 20 seconds; otherwise poll `GET /requests/{id}` (it also accepts `?wait=`), or pass `webhook_url`.

### curl

```bash
# Run the model; wait up to 20 s for the finished result in the same call
curl -X POST "https://api.doitong.com/v1/run/mirage-api/avatar-x/reference-to-video?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
  }'

# Still "queued" or "running"? Poll with the id from the response:
curl "https://api.doitong.com/v1/requests/REQUEST_ID?wait=20" \
  -H "Authorization: Bearer $DOITONG_API_KEY"
```

### JavaScript

```javascript
const API = "https://api.doitong.com/v1";
const headers = {
  "Authorization": "Bearer " + process.env.DOITONG_API_KEY,
  "Content-Type": "application/json",
};

// Run the model; wait up to 20 s for the finished result in the same call
let res = await fetch(API + "/run/mirage-api/avatar-x/reference-to-video?wait=20", {
  method: "POST",
  headers,
  body: JSON.stringify({
    "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
  }),
});
let request = await res.json();
if (!res.ok) throw new Error(request.error.code + ": " + request.error.message);

// Not finished yet: long-poll until it is
while (request.status === "queued" || request.status === "running") {
  res = await fetch(API + "/requests/" + request.id + "?wait=20", { headers });
  request = await res.json();
}
if (request.status !== "succeeded") throw new Error(JSON.stringify(request.error));
console.log(request.outputs.map((o) => o.url), request.cost.credits + " API credits ($" + request.cost.usd + ")");
```

### Python

```python
import os
import requests

API = "https://api.doitong.com/v1"
headers = {"Authorization": "Bearer " + os.environ["DOITONG_API_KEY"]}

payload = {
    "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3",
}

# Run the model; wait up to 20 s for the finished result in the same call
r = requests.post(API + "/run/mirage-api/avatar-x/reference-to-video", params={"wait": 20}, json=payload, headers=headers)
request = r.json()
if not r.ok:
    raise RuntimeError(request["error"]["code"] + ": " + request["error"]["message"])

# Not finished yet: long-poll until it is
while request["status"] in ("queued", "running"):
    request = requests.get(API + "/requests/" + request["id"], params={"wait": 20}, headers=headers).json()
if request["status"] != "succeeded":
    raise RuntimeError(request["error"])
print([o["url"] for o in request["outputs"]], request["cost"]["credits"], "API credits", "$" + request["cost"]["usd"])
```

### MCP

The MCP server at `https://api.doitong.com/v1/mcp` exposes the tools `search_models`, `get_model`, `quote`, `run`, `get_request`, `cancel_request`, `list_requests`, `create_upload` and `get_account`. A `run` call for this model:

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "run",
    "arguments": {
      "model_id": "mirage-api/avatar-x/reference-to-video",
      "input": {
        "audio_url": "https://content.doitong.com/audio/showcase/v3/tools/dub_es.mp3"
      },
      "wait_seconds": 20
    }
  }
}
```

## Response

Every call returns a request object. `status` is one of `queued`, `running`, `succeeded`, `failed`, `canceled`. `outputs` lists the generated files with URLs on our storage (kept forever, or 7 days with `?storage=temporary`; `storage` says which); `output` is the model's own result object with the same URLs.
